AUTOMATIC, srrurrnn FOR SANITARY CLOSET-SEATS.

Specification of Letters Patent Patented May 13, 1919.

Application filed. October 14,1915. Serial No. 55,850. y

To all whom it may concern:

Be it known that I, GEORGE EDWARD KINoH, subject of the King of GreatBritain and Ireland, residing at The Poplars, Quirindi, New South Wales,Australia, have invented new and useful Improvements in AutomaticShutters for Sanitary Closet- Seats, of which the following is aspecification. v y

This invention relates to, sanitary closets and consists in certainimprovements in seat preventing access of flies into it. The slides inwhich the shutters work are mounted on a pair of flat frame bars whichare each fixed to the underside of the seat by two screws, one of whichis set in a forked end or slotted hole in the bar in order to allow forshrink-age movement of the wood of which the seat is constructed.

The operating mechanism comprises a canting sill bar carried on pivotalrocking brackets which permit vertical movement of the sillbarinrelation to the rear portion of the seat, this sill bar is normallyheld upward by springs,and is pressed downward by the weight of a personresting on it when the seat is in use. Thegvertical movements of thesill bar are transmitted through said on line a-a and b'b Fig. 1,omitting certain parts; Fig. 4 fragment transverse section illustratingthe lap joint of the slide shutters at the meeting edges thereof; and

Fig. 5 fragmental detail plan illustrating the mounting of the framebars which carry the slides in whichthe shutters move.

A is the seat panel, B the aperture therein, C and D slide shutters, Z Zslides of folded sheet metal secured in any suitable manner to theundersides of the. frame bars F F, E upwardly flanged rear edges ofshutters C i and D, F F frame bars, f screws holding same to undersideof seat A, f forked (or slotted) ends of frame bars which permitrelative movement of the seat A and parts carried thereon so as to makethe adjust- ,ment of said parts independent of shrinkage of the seat A,G G lapping-flanges at meeting edges of shutters G and D, H H leversconnected respectively with the shutters C and D by cap studs J and Jwhich are fixed in the shutters and move in are slots K and K in thelevers H H. The

levers H H are fulcrumed on pins L L fixed in blocks set below the seatpanel, and

they are operated by pins M M which work in eyes in the ends of the pushbars N N which are connected at their forward ends to the rockingbrackets P P The sill bar Q ismounted on the rocking brackets P P whichare vertically movable on the fixed studs R R, and are pivotallyattached at S S to the forward ends of the push rods T T are helicalsprings in compression, threaded over the rods N N to which they aresecured at U U, their rear ends taking abutment against the guides V V,which are sufliciently free to allow a little lateral movement of thepush rods N N, which have not an exact rectilinear motion at the rearends owing to the curved are lugs screwed to the underside of the seatand pressingupon the slides Z Z to support them.

The shutters are normally closed as shown in Fig. 1, a fly proof jointbeing made by the flanges G G and the guidesZ Z. When the weight of aperson is imposed on the sill bar Q, said bar is depressed level withthe seat board A, as shown bythedotted line, with the result that thepush rods N N are forced backward against the pressure of the springs TT. This backward movement of the barsN N is applied to the" slottedlevers H H through the pins M M, and these levers acting on the shuttersG and D through the cap studs J and J force the two leaves of theshutters apart, moving them laterally, till clear of the seat aperture.When the pressure of the sill path in which the pins M M move. W W

bar Q is relieved, the parts are restored to normal position by means ofthe springs T T withthe .resultthat the pan is immediately covered fromview by the shutters and sealed against entry of-flies through the seataperture.

The rising sill bar device may be used with slide shutters andintermediate operating gear constructed or arranged otherwise vtliarrasshown in the drawings.

l npractiee, the seat, with the fittings deseribed, is made as a unit,Which can be -fiXed read ly over afiushing-basin or upon a casing orframeinclosing an earth-pan.

-What I claim as my invention and desire to secure-by Letters Patentis 1. ,A closet seat comprising a seat panel having an aperture therein,.a pairof shutters moyable toward and away from each other to cover anduncover said aperture, 1 guides in which said shutters are slidablysupported, a pair of levers fulcrumed on said panel at the rear thereofand connected to said shutters, apair of substantially parallel rodsconnected to aid levers and .eX- tending forwardly therefrom, and meansat the front of saidpanel connecting said rods and movable to operatethe rods to swing the levers and open the shutters.

2. A closet seatco nprising a seat panel having anaperture therein, apair of shutvters moyable towardandfaway from each other to cover anduncover said aperture, guides in which said shutters are slidablysupported, a sill adjacent the front edge of .said panel, bracketspivoted on said panel having arrns carrying said sill and other arms,and levers pivoted on said panel .and

connected to said shutters, and rods connecting said levers/t0 the lastmentioned I arms of the. sill brackets.

3. Ina closetseat, aseat panel, a canting sill adj acentthe front edgethereof, shutters slidingly mounted upon the underside of said panel,longitudinally movable rods operatively connected to said sill and tosaid shutters to open said shutters upon said .sill

being depressed by the. weightof a person upon the seat, and means toactuate said rodstoclose said shuttersand raise said sill when thelatter is relieved of the persons Weight.

ft. :Ina closet seat, a seat panel, a canting s ll ad acent the frontedge thereof, shutters slidingly mounted upon the underside of saidpanel, levers pivotally connected to said ing sillsupportedon pivotalbrackets, push rods with retiring springs articulating said brackets tosaid levers, pins on said shutters working in the slots in said levers,and channel guides for said shutters.

6. The combination of a closet seat panel having, an aperture thereinshutters movable toward or away from each other to cover or uncover saidaperture, supports in which sa d shutters are slldably mounted, leversfulcrumed on said panel at the rear end thereof and connected to saidshutters, substantially parallel rods connected to said levers andextending forwardly therefrom, guide means for each of said rods on saidanel SJIiH means attached to each rod and to said guide means, andpivotally mounted means at the front. of the seat panel connected tosaid rods to actuate the same.

7. A closet seat comprising a seat panel having an aperture therein,shutters movable toward or away from each other to cover or uncover saidaperture, supports in which said shutters are slidably mounted, a silladjacentthe front edge of said panel, levers fulcrumed on said panel atthe rear end thereof and connected to said shutters, substantiallyparallel rods connected to said levers and extending forwardlytherefrom, bell-crank connections between said rods and said Slll, guidemeans for each of said rods on saidpanel, and spring means attached toeach rod andlto said guide means, said latter meansoperating to closesaid shutters and raise said sill when same is relieved of a personsweight.

In testimony whereof I have signed my name tot-his specificationin thepresence of two subscribing witnesses.
